Abstract: BURNER AND METHOD                 Abstract of the Disclosure An industrial burner having an axial recirculation flame with active vortex mixing in the combustion chamber and method.      The invention relates to an improved industrial heat-ing burner and method.  The burner is of the type used to fire industrial furnaces for a number of applications, including melting aluminum, heat-treating and normalizing metal parts, and firing ceramics and glassware.  The burner efficiently burns gas or No. 2 through No. 6 fuel oils or combinations of oil and gas.    Violent intermixing of the fuel and gases in the burner combustion chamber is achieved by generating seed vortexes at a number of locations spaced around the combustion chamber, amplifying the seed vortexes and flowing the enlarged vor-texes through the chamber as part of a recirculation flow.          The vortexes are formed by flowing primary air and fuel and secondary air at an angle across the downstream edge of a cone separating the flows so that the flows shear against each other.   The vortexes are amplified by the shearing flows as they move downstream from the edge for active intermixing of the flows.  The vortexes are stabilized by high-pressure secondary air flows spaced around the circum-ference of the burner.    The active intermixing of the constituents within the combustion chamber forms a very intense and efficient flame.  The flame has a high exit velocity which is

The articulated probe mechanism is mounted on a traversing roll grinder carriage, is automatically positioned over the test roll in response to control means initiated by the grinder operator, and has a probe head with a controlled fluid bearing, air or liquid, to automatically maintain probe-head-to-test roll gap.  One or multiple eddy current, or ultrasonic, probes in the test head generate anamoly test signals, which, together with a probe head temperature sensor signal, are processed in a modified test instrument and the computer.  Computer plots defects signals as color bars vs. probe position and displays these bars graphically and other messages on a color CRT display and/or a graph printer.  This system arrangement provides for effective roll surface defect inspection by grinder personnel, and others, who ordinarily are unskilled in NDT test and analysis methods.

Abstract: LASER ACTIVATED POLYSILICON CONNECTIONS FOR REDUNDANCY            Abstract of the Disclosure An integrated circuit is fabricated with some redundant capacity by forming potential electrically conducting links which can subsequently be made electrically when extra circuit capacity is required.  Field oxide is grown on a silicon substrate and then a layer of polysilicon deposited over the oxide.  At the redundancy sites where electrical connections may subsequently be made, an anti-reflective silicon nitride coating is deposited and photodefined.  The areas of this coating are used as masks in order to diffuse dopant into the polysilicon at parts of the polysilicon laterally adjacent the redundancy sites.  When later it is necessary to bring spare capacity into the circuit the complete circuit is scanned with a continuous wave laser.  The laser melts the polysilicon under the nitride mask permitting the dopant to diffuse from the adjacent parts of the polysilicon and so form a conducting link.  However under parts of the polysilicon not covered by an anti-reflective coating the polysilicon is not melted by the laser beam and so its conductivity remains unchanged.  The fabrication process is self-aligned since the intrinsic or undoped region of the polysilicon is the same as the region which is melted.  The method for making the electrical links does not require precise positioning and focussing of the laser beam as in known methods.                           - i -
